Yes potential energy becomes kinetic energy and that is taken care of
by friction during reentry.

And thus we have come full circle and forgotten the original question,
which was why does the shuttle have to land so fast.

Jim here is the original post. Has nothing to do with landing:

"Just watched a show on the Columbis disaster, and a question came to
me.

Why does the shuttle have to be travelling so fast to re-enter the
atmosphere?"

If the shuttle re-enters the atmosphere, what maneuver is it going to
performing other than landing since at that point it has little to no
fuel, is a brick until the air gets thick, a glider thereafter, and
nowhere to go but down?

Jim, the original question is as stated previously. That the Shuttle
will land after reentry is not the point.

And once again we have been saved from the horrors of paraphrasing by
the courageous Captain Semantics and his trusty sidekick The Punctuation
Kid.

Having been suitably chastised, I scurry in search of a multi-windowed
newsreader to ensure every turn of a phrase, nay every letter and comma,
is 100% pristine in any followup.

Once the shuttle pilot hits the button to start the retro burn, you can
call it a de-orbit burn, reentering the atmosphere, landing, going down,
or break out the skillet and pork chops mom 'cause I'm coming home.
